ConstructioirrV for automatically tying,

whch'wilfl positively; insurethe ends of thewires against being pulled apartr under tension.

Attemptsl have vheretofore been made tomake or construct1 an automatic wire tying or twisting mechanism by twisting the endsl of wires to?.

gethexgjbut these attemptshavebeen failures duel to .theV fact that expansion of the compressedbale places undue tension on the wiregbands and ther twisted endsoi such Wires under the vexpansion of i the talek Acauses the twisted` ends to. become llliwSGed and Sepa'rated,

It is, therefore, one 'ofthe primary objects of the present invention to Vnot only overcomethese difliculties,l but to also. provide a vnlvel andfimproved construction. of. an, uwmaticwre balilla mechanism inwhich 'laps from two, reels of wire' on the opposite sides of 'the 'baler are broughttO.- gether; subsequently twisted 'into' twol Atv vistedi portions; then severed between the two twisted portions'gfoliowed by kinking or'bending of the Y twisted portionsso that when tension is placed 01.1y the. bandsv in the. .process of; forming the bale, the kinks or crank-like formation inthe twisted portions ofjthewiref'orms effecta 'crankfand under tension-of the expanding bale, will par-` tiallyrevol've in cranklike fashion soastolockA itseti. against. one 0f the Straight portions ofL the` wire to prevent further unwinding;

A'furtherjobject of the invention is to. provide a construction oi an automatically actuatedwire tying or twistinggmechanism which twists two strands of wire vat their intermediate portions into two twisted sections, then severs the twisted sections of' wires apart and subsequentiybends or kinks each ofY the resulting twisted ends vinto hooks or cranks, after which 'the cranks revolve tovv become lockedgupon the straight portions of the wire whenthejbands surrounding the bale are placed under tensionfbythe expandingbale,t to thereby prevent the ends of they wires from becoming untwisted,

A; further' object of the invention is to provide anovel; and improved construction of an auto-v matic wire twistingv or wire knotting'mechanisrn fora hay baler, in which the clutch ofthe twist.- ing-,mechanism .is arranged to make one complete, cyclev of operation before the shuttle anto'- matically 'disengages' itself from the knotting` or twisting mechanism. and 'thereby `permits the shuttle to remain in contact momentarily with l thefknotting mechanism bero-reif; isyreturnedto its normal inoperative position outside the hayF compression chamber. i f

In order to illustrate the construction for carrying out my improved invention of an automatic wire twistingor knotting mechanism for a baling press of the stationary or pick-up type, I have shown the same in connection with a fragmentary portion of the baling chamber, together with its associated structure. Only such parts that are common or essential to the stationary and pick-up baler and cooperate with my invention are shown in the drawings. Other parts, such as the reciprocating feeder which is synchronized with the plunger and alternately feeds the hay downwardly into the-hailing chamber 0n the return movement of the plunger, have been eliminated from the present drawings for the purpose of clearnessj. 1

In illustrating one form of my invention, I

have shown the same in connection with the more or less conventional form Ofhaybaler generally indicated by the reference character and comprises horizontally spaced top main frame members or angles 26 and 2 which extend longitudinally throughout the baling chamber and extension thereof. Spaced vertically below each of the angle members 2B and 21 are longitudinally extendinglower main frame members or angles 29. Extending throughout the compression chamber and the extension thereof and secured to the opposite angle members 29 is a sheet metal bottom 30. Reinforcing the lower angle members'29 are supplemental main framev or angle members 32. Located between the upper and lower angle members and secured to the inner sides thereofare sheet metal side walls 33 and 34 forming in effect the compression chamber. Reciprocably'mounted in the compression chamber is a plunger, generally indicated by the reference character 35. The plunger head of the plunger 35 has three vertically spaced horizontal slots 33', 34 and 35 for permitting the shuttle to move transversely on the withdrawal of the plunger from the compression chamber in the manner hereinafter described. Pivotally connected as shown at 36 to the plunger 35 is a pitman bar 31. The pitman bar is connected to the usual crank operated transmission mechanism which in turn may be operatively driven from the 4 by the stationary or pick-up type of hay baler in the manner well understood in the art.

The construction thus far described is the parts that are common to the conventional type of hay baling press of either the stationary, portable or pick-up type. Reinforcng and bracing the main frame members are opposite vertical angle braces 38. Reinforcing and bracing the top angle members 25 and 2l and extending from the vertical braces 38 are supplemental angle main l frame members 39and 46.

This mechanism includes a transversely and intermittently reciprocable shuttle, generally indicated by the reference character 4I, and shown in detail in Figs. 19 and 20 of the drawings. This shuttle 4| consists of, in effect, two vertically spaced apart and horizontally positioned shuttle members 42. Each of the two shuttle members conveys a wire across the baling chamberand is operable with the separate knotting or twisting mechanisms Vfor tying or twisting the two separate spaced apart bands about the bale on each occasion that the ,shuttle is actuated across the baling chamber as'shown in Fig. 18 of the drawings. In this connection it will be noted that each wire band about the bale has two knots or twistedportio'ns. This is necessitated by the fact that at the conclusion of binding the wire band around one bale, the wires from the reels on the opposite sides of the baler must be secured together for the next succeeding bale. These two shuttle members 42 are rigidly held together by a longitudinally'extending vertical plate as shown at 43. The plateV 43 secures the intermediate portions of the members 42 together and terminates some distance short of both ends of the shuttle members 42. the shuttle members are further reinforced by a connecting brace 44. The inner-ends of the shuttle members are provided with' recesses or cut out portions as shown at 45 so as to provide oppositely andV forwardly as Well as vertically spaced projecting points as shown at 46. The

opposite edges of eac-h of these shuttle members 42 are provided with longitudinally extending wire grooves 47 which extend to the inner ends of the shuttle members and yterminate in enlarged and relatively deep transverse recesses or grooves between the vertically spaced pointed portions 4t of the shuttle members 42 for holding, guiding and forcing the baling wire into the slots of the wire twister pinions hereinafter described. 'Ihe shuttle member 4| is provided with a clutch trip finger 48 which is welded to one side of the plate 43 and extends parallel to each of the shuttle members 42. The inner end of the nger 45 projects to a point substantially in line with the inner ends'or points 46 of each of the shuttle members 42. In order to retain the wire in one of the longitudinal grooves 47 of each of the shuttle members 42 vertical wire retainer guides or bridges 4l and 42 are provided. The retainer guide 4 i is located adjacent the forward end of each of the shuttle members and the wire retainers 42'. Vare spaced apart and located adjacent the outer end of each ofthe shuttle members.

The outer end of theV shuttle 4l is pivotally connected to substantially parallel link members generally indicated by the reference characters 49 and 5G. vertically spaced apart triangular bell-cranks The outer vends of The link 50 is in the form of two Whichi aref rigidly .held` togetherV in; A,spaced relai tionv with: respectutoreachigctherhitcrertically exe` tendin members; Fl?, ,and :5,1 The member; 15.4-

nectedzto the bar 85 and the other "end thereofV connected as shown at 94 to a bracket 95 projecting laterally from and secured tothe angle member 40. VSecured to the top surface of the tripping arc'l is an upwardly extending pin 9B which is adapted to move into the path of and engage the edge of the metering bar 86 to disengage the notch 88 of the bar from the roller B of the tripping arc when the same has been moved sufficiently forward.` The tripping arc 8| and post are normally actuated about their respective pivots S5 and 15 by a spring 91 which has one end connected to the main frame angle and the other end connected to the tripping arc 8| as shown at 98. This spring 91 actuates the tripping arc in a clockwise direction as viewed from Fig. l of the drawings and its movement is limited in this direction by a downwardly pron jecting lug or pin 99 whichengages the forward edge of the post 15. The bell-crank 55| and its associated roller 55 are held spring pressed against edge of the post 15. The bell-crank and its aspiv'otally connected, as shown at HH, to the upper triangular bell-crank and the other end thereof extending through an aperture |52 located in the outer end of a transverse bar |83 secured to the opposite angle frame members 39 and B0. Embracing the rod |08 forwardly of the bar |03 is a compression spring |54, the tension of which may be adjusted by a nut |85 mounted in threaded engagement at the forward end of the rod |08. Therod |58 is provided adjacent its forward end` with a shoulder or flange |65 which is adapted to engage one end of a spring |511 surrounding an intermediate portion 0f the rod.

The other end of the spring |91 is adapted to engage theJ transverse bar |03 to place the bellcrankv under tension when the operative parts are in the position shown in Fig. 5 of the drawings to assist in returning the shuttle' member 4| vto its normal or outermost position, as shown in Fig. l of the drawings.

From the above description it will be seen that when the operating parts are in the position shown in Figs. 1 and 2 of the drawings, on each reciprocati-on of the plunger 35 the actuating bar 68 will be similarly reciprocateo'l, but the bar 68 will be ineffective to actuate the shuttle 4| by reason of the fact that the tiltable member 15 engages the upper roller of the bell-crank 55 to hold the lower roller 55 out of engagement with the recess 12 in actuating bar 58. However, when sucient hay has been compressed in ther compression -chamber and extension thereof,so as to actuate the metering wheel 95 from the position shown in Fig. 2 of the drawings to the position shown in Fig. i of the drawings, the shuttle then will be actuated by reason of the tripping mechanism and associated parts in the manner as follows: When the metering wheel 98 is revolved by reason of a suilicient amount of compressed hay engaging the same, it will actuate the bar 85 forwardly s'o that the notch 88 thereof engages the Iroller 85 in the tripping arc 8i, causing the tripping arc to rotate about its axis Si) on the post 15 in a counter-clockwise direction. As the tripping arc 8| is revolved, the cord-like portion 82 thereof, engages the pin 83 of the actuating bar so that a further movement of the arc under these circumstances tilts the post 15 rearwardly about its pivot 16, removing the end of the post from the path of the roller 5B on the bell-crank 50 and permitting the roller 55 to -be seated in the recess 12 of the actuating bar 88. In this connection it will be notedthat the spring vii |04 is under" compression, as shown in Figs. i and 4 of the drawings, and therefore actuates the roller 55 and bell-crank 50 into operative engagement with the actuating bar 68. In Fig. 4 of the drawings, the tiltable post 15 and tripping arc `8| are shown actuated to the position preparatory to permitting this engagement of the roller 55 of the bell-crank 58 to engage theV rec-ess 12 in the `actuating bar 5S to actuate the shuttle transversely of the baling chamber, simultaneously with the return or forward movement of the plunger 35. `As the metering bar 85 is moved or advanced further forwardly by the engagement of the metering wheel with the moving bale, the

pin 96 on the tripping arc Sl engages the edgev of the bar 85 at a `pointadjacent the notch 88 therein to disengage the notch 88 from the roller 85 so as to permit the tripping arc to return to its normal position with respect to the post 15 or the position in which the pin S5 engages the `forward edge of the post 15. As this occurs the spring 91 not only normally returns the tripping arc 3| to its normal or stopping position but also returns the post 15 toits normal or forward position in which the leg of foot 18 of the post 15 engagesrthe bracket to resume its normal position, -or the position shown in Fig. 1 of the drawings preparatory to holding the roller 55 of the bell crank 50 out of engagement with the notch 12 of the actuating bar 58. It will be observed by examining Fig. 5 of the'drawings that when the shuttle 4| is actuated across the baling chain-v ber. by the return movement of the plunger 3'5, the roller 55 of the bell-crank 59 will become ydisengaged from the slot or recess 12 inthe actuat- -ing member S8 .as shown in Fig. 5 of the drawings and when the roller becomes thus disengaged it will ride along the straight edge or guide 13 of the actuating bar 53 to momentarily hold the shuttle member 4| in position to support and hold the Wires in the knetter housing during the wire twisting, wire severing and wire bending operations in the manner hereinafter described.

It will also be noted that when the bell-crank 56 is actuated to the position shown in Fig. 5,A it compresses the spring |81 on the rod |85 so that when the roller v55 of the bell-crank 50 reaches the rear'end Vof the straight porti-on 13 the spring will actuate the bell-crank 5B about its pivot 5| so as to place the roller 55 of the bell-crank 55 in position to engage the shoulder 14 of the actuating bar 58 to return the bellcrank 50 and shuttle 4| from the position shown in Fig. 5 to the position shown in Fig. 1 of the drawings preparatory to again actuating the shuttle mechanism when the next bale is to be tied.

The mechanism for supporting, feeding and controlling the wires for binding or b'aling the bales of hay from four reels of wire will'next be described. The inventicn'in the present instance provides for the tying or twisting of two spaced apart bands on each bale by two identical knotting-or twisting mechanisms which operate slmultaneously in cooperation with the two shuttle.

members 42 of the shuttle 4| so as to place two spaced apart bands on ea-ch bale of hay in the manner shown in Fig. 18 of the drawings. In

this connection it will be noted that each of the bands is provided with two twists or knots located' on one side of the bale at points adjacent the opposite ends. This is necessitated by the fact that the wire supplied from each of the reels on one side of the baling chamber must be bound to the wire from each of the reels on the other side of the baling chamber at the conclusion ofzibinding offonefbale; and. ther-beginning of the :next-succeeding bale. To .accomplish this oneach actuation. of theshuttle -acrossithe bal-- ing chamber a double twist of the wires forming the'V upper.' and lower bandsY is secured andV subsequently -cutin sectionsioneof which forms the finaly knot in the bound bale andthe other of which forms the knotfor connecting the opposite wiresztogether preparatory to receivin-tand sup,- porting-therst vchargeof .hay forthe .next succeeding bale.VV TheA manner in which; this isaeoomplished. will. hereinafter be more.,zfully der scribed.. f

Journaled on the l'free'A-d o'f Vthe'pavvl |45 is a roller |46. -The^roller|46 The gear |42 of the clutch member |48 meshes with and operatively drives upper and lower gears |48.v These separate gears |48 form part of the driving connection for operating each of the separate wire twisting, severing and bending mechanisms for the separate bands that arev bound about each bale. The gears |43 have oppositelyA disposed spindles or stub shaits formed integrally therewith, as shown at |49, which are journaled in the oppositely disposed bearing portions formed integrally `with the housing sections |34 and |35. Secured to and projecting from the opposite faces of each of the gears |48 are pins |5| having opposite rollers |52 journaled thereon. These rollers lie in the path of and are adapted to engage and actuate the respective wire severing and wire bending or kinlring mechanism in the manner hereinafter described. Meshing with' and operatively driven by the respetive upperand lower gears |48 are wire twisting pinions, generallyindicated'by the reference character |53. These wire twisting pinions have oppositely disposed disc-like hubs |54 which are journaled in aligned apertures formed in the opposite and spaced apart supporting plates or bars |55. (See Figs. 7 and 8 of the drawings.) The pinions |53`have nine teeth while each of the gears |42 and |48 have forty-five teeth so that upon one revolution of the intermittently driven clutch member, the `wire twister pinions will make five revolutions to effect a twisting of the Wires. These pinions are provided `with* radially projecting wire twisting grooves or tapered recesses as shown at |56, which extend from the base of'and between two adjacent teeth of each of the pinions and extend in a converging forni to approximately the axial center of each of the pinions to form semi-circular portions as shown at |51 for receiving the two strands of wire conveyed thereto by the shuttle members 42 'of the'shuttle 4|. (See Figs. 6, 9, 10 and 11 of the drawings.) The semi-circular portion |51 is or" reduced diameter and is slightly larger than one diameter of the wire so that it will hold the two wires in effecting the twisting operation. The portion of each of these pinions |53 adjacent the reduced slot |51 cooperates with the knife hereinafter described to shear the wires during the cycle of operation of this mechanism in the manner hereinafter described. In alignment with the radially extending slots in each of these pinions when these pinions are in their normally stopped V.position or the position shown in Figs. 7 and 8 of the drawings, are horizontally disposed slots |58 formed in the opposite plates |55. The upper and lower surfaces of these slots diverge 0r are curved outwardly so as to guide the Wires carried by the shuttle members into the slots in the respective pinions.

Projecting outwardly fromv each of `the plates |55 adjacent `each of thev at a point adjacent the slot |51 in each of the pinions |53, is a knife |63. The knives |63 are held in their uppermost or inoperative position Iby springs |54 which'have one of their ends, as shown at |55, connected to each VOf the knives and their other ends connected to pins |55 projecting from both sides oi the plate |55 and secured thereto. Spaced laterally fromeach of the wire twisting pinions |53 and secured to one of the sides of one of the plates |55 is an anvil |61 which has its upwardly extending hook-like portion |68 located adjacent the vinner end of the slot |58 of one of the plates |55 for supporting one endof the severedtwisted wire sections pre" paratory to bending or kinking the same in the manner hereinafter described. Pivoted on each of the pins |59 outside each of the anvils |51 and also on each of the pins |65 on the opposite sides of the plates |55 are wire bender arms |39 andi |10 respectively. The bender arms |69 and lit! are normally held upwardly or in their inopera-A tive position by springs |1| and |12 respectively.. The upper ends of thesesprings are connected?. tothe transverse pins |65 and their lower ends'v to the respective bender arms. The operating: knives |63 and wire bender arms |59 and il are actuated to perform Vtheir respective func-I tions in that order by the rollers |52 carried by' and on the opposite sides of the respective gears: |43 as the wire twister pinions |53 lapproach. the: conclusion of their nfth revolution by reason oi' the intermittent clutch member concluding a single revolutionV or cycle of operation. The knife mem-bers |53 are initially actuated by havu ing the rollers |52 engaging the curved arms or cam portions |12 of the respective knives |33. Following this operation and in close proximity thereto, the rollers |52 on the opposite sides of the respective gears |53 engage the camming or curved surfaces |13 ofr the opposite and respective wire benders |69 and |13 as clearly shown in Figs. 10 and 13 of the drawings. in order to permit the rapid .withdrawal of each of the bender arms |69 and |13 after they have accomplished their bending or kinking operations of the twisted wire sections, the cam portion |13 of each of the bending armsv terminates in an abrupt arcuate recess |14, which permits the respective springs |1| and |12 to rapidly return these bender-arms from the position shown in Fig. 10 to the position shown in Fig. 16 to thereby permit the easy and rapid withdrawal or freeing of the kinked twisted ends of the wires from the position shown in Fig. 13 to that shown in Fig..14 of the drawings. Located in the path of and adapted to engage the lower surface of the reciprocable shuttle members 42 are oppositely disposed guiderollers |15 which are journaled on pins |15y secured to the opposite housing sections of the housing |33. The plates |55 which carry the two wire twister pinions |53 and theirassociated wire severing and wire bending mechanisms are mounted in a vertical recess |11 and bolted between the housing sections |34 and |35 of the housing |33 as clearly shown in Figs. 16 and 1'1 of the drawings. The side of the housing members |34 and |35 lying adjacent the side of the baling press frame are provided with two vertically spaced apart vrectangular and horizontally disposed openings |18, the centers of each of which lie in planes parallel with planes of each of the centers of the wire receiving grooves of each of the wire twister pinions |53 when these pinions are in their home or norrnally stopped position as shown in Fig. 16 of stepsiby which this method is accomplished.

By. referring to Figs. 11 to 15 inclusive, the successive Asteps are shown in their proper sequence. In Fig. 11 the shuttle member 4! carries one strand of the wire I I2 on one side of the baler into contact with the other strand of the wire 129 on the other side of the baler and both strands oi wire are simultaneously forced by the shuttlei into the slots on the wire twister pinions 153 after which the pinions are revolved ve complete revolutions and the twisted wires assume the position and formation of two twisted sections on each side of each of the pinions with .the outer ends of the twisted sections supported in the grooved or slotted pointed ends d of the shuttle 4I. in this position the pointed ends of the shuttle members serve the function of anvils during the bending operation. Thev next successive step in the method is the severing operation by each of the knives 163 which operate their respective shearing edges adjacent one side of .each of the slots in the respective twister pinions 153. The third step in my improved method is disclosed in Fig. 13 of the drawings in which the opposite bender arms |69 and |70 are actuated to place a kink or bend iny each of the severed twisted sections of the wire. One of each of these sections is kinked or formed by each of the bender arms IBS by having the opposite ends supported by the slots of the respective wire twister pinions |53 on one sideand the otherends of the twisted sections supported in the slots between the pointed ends 4 of the shuttle M on the other side. The next step in my improved method is shown in Fig. 14 where the kinked or hook-like section is released from the position after the kinking operation'prepara tory to assuming its position as part of the 'band embracing the bale. After the bale is discharged from the compression chamber of the baler the expansion of the hay in the bale will causeV the Wire band to be placed under tension and when tension is placed on the wires, the bent or kinked ends of the twisted sections will revolve in a ycrank-like fashion until they strike the straight portions of the wire bands so as to lock themselves thereagainst, in the manner disclosed in Fig. 15 of the drawings. When the twisted ends of the wires stop against the straight portionof the bands in the manner shown in Fig. 15 of the drawings, they form stops and prevent further untwisting so that further strain on the wire bands will break the bands or wires in some other place rather than untwist the twisted ends.

The operation of my improved novel wire knot ting or twisting mechanism is synchronized with a shuttle mechanism and the reciprocatory plunger in the manner hereinbefore described so as to perform their respective functions in proper order. l

From the above description it will 4be seen that I have not only provided a novel and improved construction of a wire knotting or twisting mechanism for securely fastening the ends of wire bands together, but also a novel method of accomplishing this object. The invention is adaptable for use in connection with any-kind of hay baler, but is especially advantageous for use with the stationary, portable or pick-up types of hay balers.

While in the above specification I have described certain steps of my improved method and constructionY of an automatic wire twisting or tying device for baling hay, it will, of course, be understood that variations both in the method and construction may be employed without departing from the spirit and scope of the invention as expressed in the appended claims.
